CPU #1 provides Riser Slot #1 with x16 PCIe bus lanes which can be bifurcated to support multi-slot riser
cards.
The number of PCIe lanes routed to Riser Slot #2 is dependent on the system configuration. In a single
processor configuration, CPU #1 will route x8 (default) PCIe bus lanes to Riser Slot #2. However, should the
system be configured with an optionally installed 8-port Intel
®
C600 Upgrade Key, four of eight PCIe bus lanes
from CPU #1 will be routed via a multiplexor to the Intel
®
C602 chipset to support the embedded 8-port SCU
SATA/SAS controller. With CPU #2 installed, an additional x16 PCIe bus lanes are routed to Riser Slot #2. All
available PCIe lanes routed to Riser Slot #2 can be bifurcated to support multi-slot riser cards. See the
following diagram to determine PCI bus lane routing for each riser card.
